iTop review 2026: an in-depth look at this open-source ITSM and CMDB platform by Combodo, its features, editions, pricing and top alternatives.
iTop is designed to give IT operations teams a single, web-based system for tracking both what their IT environment consists of (through its CMDB) and how they operate and support it (through ITIL-aligned incident, problem, change and request management). Rather than treating asset tracking and service desk ticketing as separate tools, iTop ties them together so, for example, an incident ticket can be directly linked to the specific server or application configuration item it affects.
The platform is developed by Combodo, a French software company founded in Grenoble in 2010 by Erwan Taloc, Denis Flaven and Romain Quetiez, and now based in Echirolles near Grenoble. Combodo has grown iTop to more than 2,900 organizations worldwide while remaining a relatively small, focused team of roughly 11 to 50 employees.
iTop's core is released under the AGPL-3.0 open-source license and can be freely downloaded, self-hosted and modified, with Combodo generating revenue instead from paid, supported editions (Atelier and Forge) and professional services for organizations that want a managed or heavily customized deployment.
At the heart of iTop is its CMDB, which tracks IT assets -- servers, applications, network devices, and the relationships and dependencies between them -- giving support teams visibility into what an incident or change might impact before they act. This CMDB is fully customizable through iTop's low-code data model designer, which lets administrators add new object classes, fields and relationships without writing PHP code.
On the service management side, iTop covers the core ITIL processes: incident management, problem management, change management, and a self-service portal where end users can submit and track their own requests, backed by a knowledge base and configurable SLA tracking for measuring response and resolution performance against targets.
Extensibility comes through a REST/JSON API for integrating with monitoring tools, LDAP directories and SSO providers, plus 'iTop Hub,' a community and Combodo-maintained marketplace of add-ons and extensions that plug additional functionality -- from specific integrations to industry-specific workflows -- into the core platform without forking the codebase.
iTop Community, the free open-source edition, is unrestricted and recommended for teams of roughly 10 or fewer agents running the platform on-premise; there is no license fee and no artificial feature-gating built into the free tier. This makes iTop one of the few genuinely full-featured, no-cost ITSM platforms available for small IT teams.
For larger deployments, Combodo sells iTop Atelier (targeting teams up to roughly 50 agents, available on-premise or as SaaS) and iTop Forge (targeting 50-plus agents needing deep customization and industrialized support, also on-premise or SaaS), but neither edition's pricing is published; both require contacting Combodo directly for a custom quote based on agent count, deployment model and support level.
Yes, iTop Community is a free, open-source edition under the AGPL-3.0 license, best suited to teams of around 10 agents or fewer. Larger teams can upgrade to the paid Atelier or Forge editions.
